Hi,
It turns out the xmms is not able to read audio from CD's due to a removed
IOCTL. cdparanoia is however able to read audio from CD's after a recompile
including libcam.
static int
cdrom_read_audio(int cdfd, int lba, char *buf, int btw)
{
int rtr = 3;
do {
struct ioc_read_audio ira;
ira.buffer = buf;
ira.nframes = btw;
ira.address_format = CD_MSF_FORMAT;
ira.address.msf.minute = lba / (75 * 60);
ira.address.msf.second = (lba / 75) % 60;
ira.address.msf.frame = lba % 75;
if (ioctl(cdfd, CDIOCREADAUDIO, &ira) >= 0)
return ira.nframes;
} while (--rtr >= 0);
return -1;
}
The "CDIOCREADAUDIO" is not implemented in the FreeBSD 8/9-current kernel from
what I can see.
